ROLLING-MILL.

SPECIFICAIIJION forming part of Letters Patent No. 417,484, dated December 17, 1889.

Application filed October 24, 1889. Serial No. 328,089. (No model.)

To all whom t may concern.-

Be it known that I, PATRICK F. HANLEY, a citizen of the United States, residing at I-Iomestead, in the county of Allegheny and State of Pennsylvania, have invented or discovered a certain new and useful Improvement in Rolling-lVIills, of which improvement the following is a specification.

In Letters Patent No. 352,748, dated November- 16, 1886, and in applications numbered and iiled as follows: Serial No. 296,571, January 17, 1889, and Serial No. 321,261, August 19, 1889, respectively, are described and claimed certain mechanisms for shift-ing the'table-s u pporting carriages and for raising and lowering the tables employed in rolling-mill plants for felelding the material to be operated on tothe ro s.

The invention described herein relates to certainv further and additional improvements in mechanism for effecting such movements.

In general terms, the invention consists in the Vconstruction and arrangement of mechanical devices or elements, all as more fully hereinafter described and claimed.

Inthe accompanying drawings, forming a part of this specification, Figure 1 is a plan View of a rolling-mill having my improved carriage-shifting mechanism applied thereto. Fig. 2 is a similar View of a mill, showing a modified arrangement of the carriage-shifting mechanism. Fig. 3 is aplan view of a rollingmill having my improved table-lifting mechanisln applied thereto; and Fig. 4 is an end elevation of one of the carriages and tables, showing the table-lifting mechanism.

In the practice of my invention two pairs or lines of rails 1 and 1fL are arranged on each side of the rolls A, parallel with the axes of said rolls. On these rails are mounted suitable trucks having frames 2 2 secured thereto, said frames and trucks forming carriages for the tables 3 3. The tables 3 3 consist, as set forth in said Letters Patent and applications hereinbefore referred to, in side plates having feed-rolls mounted therein, said rolls being driven by a suitable train of gearing secured to the ends of said rolls. The tables are pivot-ally mounted at or near their outer ends upon the carriages, so as to permit of the vertical adjustment of the ends of the tables adjacent to the rolls A. In order to an anti-friction roll 6, upon a Wire rope 7.

This rope is secured at one end to a post 8 or other suitable anchor and passing over antifriction rolls on the upper ends of standards lO, attached to the sides of the carriage-frame 2, and under'the arm 4 is attached at its opposite end to a drum 11. This drum and the post or anchor 8 are so located at or beyond the opposite ends of the' lateral traverse of the carriage as not to interfere with the movements thereof. The arm 4 and standards 10 are so proportioned as to their relative lengths that when the rope is tightened by the rotation of the drum, so that the portion between ously by the same cylinder, as itis desired that simultaneous and equal movements of both tables 3 3 should be had; but it will be readily understood that the drums may be actuated by independent cylinders. The arrangement of the rope over the standards 10 and under the arm 4, without any attachment to said parts, permits of the free lateral movements of the carriage without changing the vertical position of the table.

For shifting the carriage laterally, drums 15 are mounted on the carriage, near the ends thereof, and around said drums are passed two .or three turns of ropes 16, whose ends are attached to posts 17 o'r other suitable anchors located at points a little beyond the limits of traverse of the carriage. On the 'shafts of the drums 15, which are mounted in suitable bearings on the carriage, are keyed pinions, (shown in dotted lines in Fig. 1,) which intermesh With rack-bars 18, connected to the piston of the cylinder 19, said cylinder being secured to the carriage between the IOO drums, and provided with piston-rods extending through the heads of the cylinder. By the movements of the piston in the cylinder the drums may be rotated in either direction, thereby winding the ropes on one side of the carriage and moving the latter in that direction while the ropes 011 the opposite side are unwound.

In the arrangement in Fig. 1 the carriages 2 2 are moved independently; but as it is desirable at times to shift both carriages simultaneously provision is made therefor by placing drums 19 19 at one end of the lateral movement of the carriages, and around these drums are passed two, three, or more turns of the ropes 2O 21 and 20 21, respectively, as shown in Fig. 2. The rope 2O on one side of the drum is passed around a guide-pulley 22 and its end secured to the side of the carriage, at the inner end thereof, while the p0rtion of the rope leading from the opposite side of the drum is passed around `guide-pulleys and 2l and its end connected to the opposite side of the carriage, at or near the outer end thereof. The rope 21 is correspondingly arranged-that is to say, the portion leading out from one side of the drum is passed around the guide-pulleys 25 and 2G and its end secured to the inner end of the carriage, while the other portion of said rope is passed around the pulley 27 and its end secured to the outer end of the carriage. It will be observed that the ends of each of the ropes 2O and 21 are attached to opposite sides of the carriage at opposite ends thereof, and that the ropes are so wound around the drum that on the rotation of the latter the portions of the rope attached to one side of the carriage will be wound up, while the portions connected to the opposite side are paid out. rlfhe ropes 20 21 for operating the carriage 2 are similarly arranged. The drums 19 19 have pinions 2S 28 keyed to t-heir shafts, said pinions engaging rack-bars 29 29, which are connected to the piston-rods of the fluidpressure cylinder 30. The racks are so arranged that by their movement in one direction by the piston of the cylinder 30 the drums will be so rotated as to shift the earriages equally in the same direction.

It will be understood that the means shown in Figs. 3 and 4: fol' raising and lowering the tables can be used in connection with either of the means hereinbefore described or with any other suitable means for shift-ing the carriages laterally, and also that any suitable means for adjusting the tables vertically can be employed in connection with the mechanism shown in Fig's. 1 or 2 for moving the table laterally.

The lateral movement of the carriage 2 simultaneously with the carriage 2 can he effected by connecting the carriage 2 to the carriage 2 in the manner shown in dotted lines in Fig. l, the carriage 2 being the prime motor and operated in the manner shown in Fig. 1 or in any other suitable manner.

As shown in Fig. 1 by dotted lines, i'opes 31 and 32 are connected to the carriage 2, and leading therefrom in opposite directions are passed around guide-pulleys 33, 34 34, and 35 and pass to the carriage 2 from opposite sides thereof. The arrangement of ropes for the concomitant movement of the carriages 2 2 is shown as connecting the inner ends of the carriages; but it will be understood that a similar connection is formed between the outer ends of the carriages. In lieu of connecting the ropes 31 and 32 to the carriage 2, they may be connected to the drums 15 in said carriage.

' I claim herein as my inventionl. In a rolling-mill plant, the combination of a reversible rotating drum, a flexible connection extending in opposite directions from the drum, one of said members being fixed and the other movable, and a laterally-movable carriage coupled to the flexible connection, substantially as set forth.

2. In a rolling-mill plant, the combination of a laterally-movable carriage, a reversible rotating drum mounted on said carriage, a rope or other exiblc device passing around said drum and extending in opposite directions from said drum and having its ends secured to stationaryposts or anchors,suhstan tially as set forth.

3. In a rolling-mill plant, the combination of a laterally-movable carriage, a table pivoted thereto, a reversible rotating drum, and a rope passing over standards or supports on the carriage and under an arm on the table, one end of said rope being 'connected to the drum and the other end to stationary posts or anchor on the side of the carriage opposite the drum, substantially as set forth.

-1. In a rolling-mill plant, the combination of laterally-movable carriages, reversible rotating drums, ropes passing around said drums and coupled to the carriages, whereby simultaneous movements of both carriages are effected, substantially as set forth.

In testimony whereof I have hereunto set my hand.

PATRICK F. IIANLEY.
